Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471520, here are decompositions:

11 + 471509 = 471520
17 + 471503 = 471520
53 + 471467 = 471520
113 + 471407 = 471520
131 + 471389 = 471520
167 + 471353 = 471520
239 + 471281 = 471520
311 + 471209 = 471520

Showing the first eight; more decompositions exist.
